PAPER FILE AND BINDER..

Application filed December 10,v 1920.

is a specification.

This invention has as its main object to provide a portable file in which perforate sheets of paper may be neatly and compactly preserved in condition for ready reference.

Another object is to provide means whereby the file prongs may be securely clamped when in an engaged position, but which permits easy and rapid insertion or removal of individual papers.

A further object is to provide means facilitating the transference of any desired portion of the papers en bloc, and without disarrangement of those remaining.

A still further object is to provide means `for clamping the papers on the file prongs.

These and other analogous objects are attained. by the novel construction, combination and arrangement of parts hereinafter described and shown in the accompanying drawings, forming an essential part of this disclosure, and in which Figure 1 is a perspective view showing the file and binder extended, the engaging prong elements being clamped, and` indicatingin broken lines the transfer device in operative position.

Figure 2 is a similar view of the same, exhibiting the purpose of the invention.

Figure 3 is a fragmentary sectional view taken on line 3-8 of Fig. 1, and drawn to an enlarged scale.

Figure 4 is a plan view of the parts shown in Figure 8.

Figure 5 is a sectional view taken on line 5*5 of Figure 3.

Figure 6 is a fragmentary sectional view taken on line 6-6 of Figure 1.

Figure 7 is a fragmentary side view of the engaged ends of the file and transfer prongs, drawn to a further enlarged scale.

Figure 8 is a plan view of the clamp used to hold papers on the file prongs.

Referring to the drawings in detail, the numeral 10 designates a pair of sti cover plates preferably made of heavy paste-board and covered with flexible textile fabric, this Specification of Letters Patent.

retreated .nay is, ieee. Serial No. 429,620.

fabric actingas hinges at the folding lines 11, which connect with the central element or backing plate 12, similar in construction to the plates 10.

Secured centrally of the center plate, upon its inner side, by rivets 14, is a thin metallic plate 15, bent at right angles outward along its ' edges forming uprights 16 and 17, the latter of which is extended and rolled into a cylindrical bead 18 enclosing a rod 19 in the manner of a hinge.

` The extending elements of the' rod 19 are bent to present a pair of arcuate parallel curves, constituting the Vtiling prongs 20 terininating in straight ends 21 containing central drilled openings 22.

\ Formed in the edge of the opposite upright 16 are a pair of recesses, or slots 23 receptive of the prong yends 21 when turned downward to enter the same.

An elongated spring plate 25 is held by rivets`26 to the outer sideof the upright 16, the plate having curved ends kand offset portions 27 adjacent the rivets.

Interposed between the spring plate and upright is a slide`28 having a central longitudinal slot 29, the length of the-slot being in excess ofthe distance between the rivets 27 which pass through it. The extreme ends ofthe slide 28 are bent forward forming stops 30 and 31 adapted to make contact with the ends of the upright 16 thereby lim-4 e iting the movement of the slide.

The upper edge of theslide is bent outwardly and then curved reentrantly forming an'open U shaped guard 32its upper edge being in register with the top edge of the upright 16, and in which are received the ends 21 of the file prongs, the `same passing through slots 33 intheupper portion of the guard when the slide is pushed so that the stop 30 makes contact with the end of thev upright, and when the guard and slide are moved to their other eXtreme position, the ends 21 are securely locked in the guard, and it is to be noted that the slide is frictionally vheld in either position, due to the spring plate 25. Y

The foregoing structure constitutes the simpler form of file and, as will be seen, is effective for its purpose, thesheets or leaves of paper or other material to be filed, having been perforated, are placed in position upon the connected file elements 20, which are then turned downward, through the slots B3, into the recesses 23 and the slide moved to engage their ends in a manner easily understood.

ln order to shift any considerable number ot papers from the file in a pack the Jfollowing` additional device is used.

Secured on the inner side of the cover plate adjacent the locking device, is a metallic plate 35, held by rivets 36 and having its outer elge rolled into a bead 37 loosely containing a wire or rod 38, bent to p-resent substantially straight parallel fork elements 39 turned outwardly at their ends and reduced in diameter, presenting pin-like eX- tremities 40 adapted to be received within the openings 22 of the prongs when brought into engagement, as best shown in Figs. 2 and 7, a coiled spring 4:1 encircling the rod 38 and operatively engaging one oi' the 'fork elements 39 and plate l0, acting to press the pins or spurs 40 into the ends 21 and maintain them in engagement.

lVhen these elements are not required, one of the rods is engaged below a clip 42, held by a rivet L13 to the cover plate, near the end of the rod, which, as will be understood, is sufficiently resilient to permit springing inward from below the clip when desired.

1n order to hold the loose papers compactly on the iile prongs, as shown at the right ot Fig. 2, the clamping device disclosed in Fig. 8 is used.

This device is comprised of a loose metal plate 45, having a beaded edge 46 and containing openings 47, the material removed from the openings being formed into rolls a8 used as bearings for a rod 49 bent into a central loop 50 between the bearings to be used as a handle, the ends ot the rod being turned in the same plane as the loop, forining fingers l. i

Circular openings 52 are formed through the plate, the saniebeing receptive of the iile prongc 2O whenthe plate 45 is pressed thereover and the elements 51 turned out-` ward, away from the openings 52 by properly manipulating the handle 50.

Vvlhen the plate has been pressed into position on the paper, the `handle is turned as shown, the fingers 51 forcing the prongs outwart', causing them to bind in the openings and clamp the papers firmly in position.

From the foregoing it will be seen that a neat appearing and effective iile and binder has been disclosed capable of fulfilling its purposes and that the same is of simple and inexpensive construction.

Having thus described my invention and set forth the manner ot its construction and said prongs, said rod being use, what l claim as new and desire to secure by Letters Patent, is

l. A lile comprising a plate, uprights formed at the lateral edges of said plate, apair of arcuate prongs, a rod integral with hinged in one of the uprights, the other upright having recesses receptive of the ends oi' said prongs, a slide movable on the outer side ot' the last named upright, a locking means formed with said slide into which the prong ends enter, stops for said slide and means for resiliently holding said slide on the upright.

2. A File comprising a pair ot covers, a backing plate hingedly engaged therebetween, a metal plate fixed on said backing plate, uprights 'formed with the lateral-edges of said metal plate, a pair or' prongs hinged in one ot said uprights, means on the other upright ior securing the ends of said prongs when entered therein, a forli hinged to one or said covers, outturned spurs at the ends of said forli, said spurs being engageable in openings in the ends of said prongs and a spring adapted to cause such engagement.

3. A lile comprising a pair of covers, a backing plate hingedly engaged therebetween, uprights on said plate, a pair of curved prongs hinged to one of said uprights, said prongs having longitudinal openings at their free extremities means on the other of said uprights for engaging or disengaging said prongs, a fork hinged to the cover adjacent the last named upright, said jrorlr having parallel elements terminating in spurs turned at an angle, said spurs being engageable in the mentioned openings in said prongs, a spring arranged to force said spurs towards said prongs and a clip on said cover whereby said fork may be retained thereagainst.

A. file comprising a pair of rigid covers, a rigid backingI plat-e hingedly connecting said covers, uprights extending in parallel from said plate, one of said uprights having a rolled edge, tile prongs pi'voted in said edge adapted to extend over the other upright and enter recesses therein, a guard receptive of the ends or said prongs slidably mounted on the last named upright, stops limiting the action of said guard, spring means Jfor lrictionally holding said guard in adjustment, a fork pivoted on one of the covers, means co-operative between said fork and prongs whereby they are adapted to form continuous guides for articles disposed thereon and a clip for holding said fork when not in use.

In testimony whereof l have signed my name to this specification.

HARRY BRUNDAGE.
